Adhesive coated polyester felt

Abstract

A composite laminate suitable for use in upholstery, automotive interiors and the like, which is made of a polyester felt substrate, an adhesive coating is contained on said felt substrate which obviates the need for a barrier layer for a vinyl laminate, with a vinyl film overlaying and bonding with said adhesive to said substrate. The method of making the laminate is also disclosed.

What is claimed is:  
     
       1. A soft, supple adhesive coated felt suitable for use in laminating with vinyl which consists essentially of: 
       (a) a support in the form of a sheet of felt having an upper and lower planar surface; and  
       (b) an adhesive coating contained on one of said surfaces in a concentration of about 0.05 to 0.90 oz/yd 2 , with said coating being suitable for direct bonding with vinyl said adhesive having a viscosity in the range of about 6×10 4  to 7.5×10 5  centipoise at the temperature of application whereby said adhesive does not significantly penetrate into the depth of the felt.  
     
     
       2. A soft, supple adhesive coated felt suitable for use in laminating with vinyl which consists essentially of: 
       (a) a support in the form of a needlepunch felt having an upper and lower flat planar surface; and  
       (b) an adhesive coating contained on one of said surfaces in maximum concentration of about 0.3 oz/yd 2 , with said concentration being in an amount sufficient to firmly bond with vinyl and also obviates the need for a barrier layer, with said adhesive having a viscosity in the range of about 6×10 4  to 7.5×10 5  centipoise at the temperature of application whereby said adhesive does not significantly penetrate into the depth of the felt.  
     
     
       3. A soft, supple composite laminate suitable for use in upholstery, furniture, and automotive interiors which consists essentially of: 
       (a) a needlepunch felt having two flat planar surfaces;  
       (b) an adhesive coating contained on one of said surfaces in a concentration of about 0.05 to 0.90 oz/yd 2  with said coating obviating the need for a barrier layer for vinyl; and  
       (c) a vinyl polymeric film laminated and bonded on to said adhesive layer, with said adhesive having a viscosity in the range of about 6×10 4  to 7.5×10 5  centipoise at the temperature of application whereby said adhesive does not significantly penetrate into the depth of the felt.  
     
     
       4. A felt as in  claim 1  in which the felt comprises substantially 100% polyester fiber.
